In Build Apps, Row Cells are Changing Their Width

[Ron_Hagan]

Hi,

I'm trying to create a grid, like a blank calendar where I can insert data into the cells from a data source.  I created a container and put 5 rows in it with 7 columns in each row.

The top row is where I wanted to put the days of the week as a header so I started by putting a text component in the first cell of the first row.

When I did that, the width of that cell increased, throwing off the borders of the cells for the other rows.  I tried setting the minimum and maximum width of the container, the rows and each cell within the row and it still does it.  

This is what it look like before I add the text:

And this is what it looks like when I add the text field:

Is there a way to absolutely lock the width of a cell in a row?  I know they are actually containers so I'm a little puzzled about this.

Thanks for any and all suggestions!

Ron
